4D reconstruction allows sites to be studied after excavation

Alfonso Benito Calvo, a researcher on the Centro Nacional de Investigacion sobre la Evolucion Humana (CENIEH), has coordinated a latest research revealed within the journal Digital Purposes in Archaeology and Cultural Heritage on the 4D reconstruction of paleoarchaeological websites utilizing terrestrial laser scanners and 3D processing software program, which allows their buildings to be studied even after they’ve been excavated.

Furthermore, this work, carried out utilizing the gear of the CENIEH Digital Mapping and 3D Evaluation Laboratory, exhibits how the excavation course of evolves over time and assesses the diploma of conservation of the websites, monitoring the extent of harm to the sections and surfaces not excavated.

“Our research exhibits the significance of three-dimensional and sequential documentation of paleoarchaeological excavations, for producing 4D databases (4Ddb), made up of referenced spatial information (comparable to orthoimages, elevation fashions, and 3D level grids and clouds) recorded over time, giving us the fourth dimension or 4D”, explains Benito Calvo.

The excavation course of entails the modification or destruction of web sites, in order that their 4D reconstruction is a key course of in documenting them. Within the Sierra de Atapuerca (Burgos, Spain), the Trinchera del Ferrocarril websites (Gran Dolina, Galeria and Sima del Elefante) have undergone scanning since 2012, so the geometry of the stratigraphic surfaces the place the archaeological stays are discovered could be reconstructed.

“Thanks to those strategies, we now have digital reconstructions of all of the Trinchera websites, to allow them to be studied as if that they had by no means been excavated”, provides Benito Calvo.
